When you have federal taxes withheld from your pay, this is an estimate of what you owe for the year. In your case, $2,628.32 was withheld, but your actual federal tax liability came to $2,981.55. This means that you owe more than what was withheld.
The difference between what you owe and what was withheld is:
\[ $2,981.55 - $2,628.32 = $353.23 \]
Since you owe $353.23 more than what was withheld, you must pay an additional $353.23 to the government.
The correct interpretation of the situation is: You must pay an additional $353.23.
